Quantum oscillations in the Kagome superconductors AV<sub>3</sub>Sb<sub>5</sub> (A = K, Rb, Cs)
ORAL
Abstract
The layered Kagome metals AV3Sb5 (A = K, Rb, Cs) exhibit a unique combination of nontrivial band topology, competing charge- and superconducting orders and clear signatures of electron correlations. Using thermodynamic (magnetization, magnetostriction, thermal expansion) and transport measurements, we have investigated the normal- and superconducting state properties of high-quality single crystals. Clear signatures of quantum oscillations were observed in all these quantities. The nature of the Fermi surface in the CDW state and the interplay with superconductivity is discussed in the light of recent theoretical models.
